摘要
本文对定流量、变历时运行的渠道轮灌优化配化模型进行了改进,应用粒子群优化算法(Particle SwarmOptimization,PSO)进行了配水渠道流量最优化的0-1整数规划模型求解。PSO算法采用二维数组编码方法,构造了相应的适应度函数,编制相应的计算机求解程序。计算结果表明,本文采用PSO算法的优化配水模型所得出的轮灌组引水持续时间均匀性略优于现有其他方法。
The optimization model for constant discharge but variable duration rotational distribution of irrigation channels based on 0 - 1 linear programming is improved by using Particle Swarm Optimizer （PSO） algorithm. The 2 - D array coding method is applied and the corresponding fitness function in PSO is constructed for solving the model. The program for calculation by means of computer is developed. The comparison of the calculation result shows that the uniformity of irrigation duration for rotational irrigation sets obtained by the proposed method is slightly better than that of other methods.
